Have had to replace the alternator and the replacement part, although is for the same car as the original one supposidly, appears to have 4 pins rather than 3 (this is not including the main power out terminal) Physically it is pretty much the same and fits the mount so I'd prefer to stick with this one rather then trying to source an exact replacement before the Silverstone meeting the weekend after next. The list of cars it fits is listed on the ebay page from the sale.

I've hunted for a bit to find wiring diagrams for a few of these cars with no luck. Does anyone have any idea where i might find one or is someone aware of what each pin is from experience? (Quinton Hazell part, PA646 I think)

Thanks in advance,

(yes yes, I know the ebay image shows 4 pins on the plug socket!)

This should be useful, although for my Denso alternator in the end I just tried pins until the engine loaded up a bit!

Edit: oops, that only shows the three pin version. I'd just go with trial and error...
